Hi Ady,
I was on letrozole for about 4 months, however the side effects really did affect me, like you it affected my bones and to get up in the morning I used to waddle like a duck until I straightened myself out,the tiredness as well was a bummer, just curious about the chines herbs you are taking for the hot flushes, I know that I have to be very careful with what I take as some of these complimentary treatments interact with the other drugs that we take, especially if you are er/pr positive as I am,I carry a little wooden fan with me and whip it out when I need to,that fixes things up also drinking a cold glass of water, coffee and more so alcohol are the worst offenders,my oncologist stopped the femara and put me on afinitor/aromisin combo, this also had side effects, cant win can we, from reading different posts, the side effects of femara are pretty universal, hopefully a break may improve things, I have had several breaks with different drugs and it has helped me, hopefully it will help you as well, we are damned if we do and damned if we dont!!
